For the successful design of an AMB system, proper material selection and actuator design is a must. The strength of the magnetic force depends upon the current density of the winding, actuator dimension and the gap between the actuator and the rotor. This paper presents the design of a U-O type single-actuator and a double-actuator Active Magnetic Bearing (AMB) utilizing ANSYS Maxwell 17.1 software. In double actuator AMB the actuators are placed at 180 degrees apart. In this study, Finite Element Method (FEM) based simulation has been performed for two different structures and their magnetic properties for instance- flux pattern, force, flux density and inductance are obtained for various air-gaps. Analysis has also been done with the change in current density by varying in the coil turns. The comparative results of single and double coil AMB are illustrated in 2-D and 3-D plots.
